Embedded Systems Engineer – IoT Devices

Location: Coimbatore, India | Type: Full‑time (On‑site)

About Carbelim (Linkedin)

Carbelim is a climate‑tech startup pioneering nature‑based carbon capture and utilisation

(CCU) solutions powered by advanced microalgae biotechnology. We develop AI‑driven

systems that purify polluted air, capture CO₂, and transform emissions into valuable

bio‑based products. Incubated by IIT‑Madras and accelerated by IIM‑Lucknow, we unite

biotechnology, sustainable engineering, and urban design to build a cleaner,

climate‑positive future.

Why Join Us

 Mission‑driven hardware: build products that directly improve planetary health.

 End‑to‑end ownership: take ideas from concept to certified, field‑ready devices.

 Small, expert team: collaborate with scientists, designers, and entrepreneurs who value

curiosity and initiative.

What You'll Do

 Own the complete lifecycle of IoT hardware products, from system architecture and

component selection through prototyping, testing, certification, and pilot production.

 Design electronics: create schematics, multilayer PCBs, and low‑power circuits; run

DFM/DFT and bring‑up.

 Develop embedded firmware (C/C++ or similar), including drivers, OTA updates,

bootloaders, and power‑management features.

 Interface sensors and connectivity, wiring up serial buses (I²C, SPI, UART) and wireless

stacks (BLE, Wi‑Fi, LoRa, Zigbee, MQTT).

 Prototype, test, and certify hardware, ensuring it meets functional, EMI, safety, and

regulatory requirements before field deployment.

 Collaborate on mechanics: work with industrial designers on enclosures, waterproofing,

and ergonomic wearables.

 Document & transfer: maintain BOMs, Gerbers, test procedures, and production

hand‑off packages.

 (Optional) Cloud linkage: hook devices to AWS IoT / Azure IoT Hub / custom back‑ends

nice to have, not mandatory.

Requirements (Must Haves)

 B.E./B‑Tech in ECE, CSE, EE or related branch

 3+ years delivering commercial embedded products

 Hands‑on with MCUs such as ESP32, STM32, nRF52

 Strong analog/digital design & PCB CAD (Altium/KiCad/Eagle)

 Wireless protocol know‑how (BLE, Wi‑Fi, LoRa, Zigbee)

 Power‑budgeting & battery‑powered design chops

 Ability to showcase prior IoT hardware you built (demo units, photos, or repo links

 (Nice to have) Cloud dashboards, Grafana, Node‑RED, etc.

 (Nice to have) AWS IoT/Azure IoT Core integration

Skills

 Ownership mindset; able to drive schedules and unblock issues independently

 Clear communicator who can document designs and mentor interns/juniors

 Passion for sustainability and real‑world impact

Compensation

*Competitive; commensurate with experience.*
